Receive Buffers. The number of receive buffers. Receive buffers are data segments that allow the network adapter to
allocate receive packets to memory. For 1 Gbps adapters, the range of valid receive buffers is 50 to 5000 in increments of
1 with 750 receive buffers as the default value.
Receive Buffers (0=Auto). The number of receive buffers. Receive buffers are data segments that allow the network
adapter to allocate receive packets to memory. For 10 Gbps adapters, the range of valid receive buffers is 0 to 3000 in
increments of 50 with 0 receive buffers as the default value.
Transmit Buffers (0=Auto). The number of transmit buffers. Transmit buffers are data segments that allow the network
adapter to monitor transmit packets in the system memory. The range of valid transmit buffers is 0 to 5000 in increments of
1 with 250 transmit buffers as the default value.
TCP Connection Offload (IPv4). Enables and disables TOE offload when using the IPv4 protocol. The default is Enabled.
TCP Connection Offload (IPv6). Enables and disables TOE offload when using the IPv6 protocol. The default is Enabled.
Pause on Exhausted Host Ring. For BCM57711 and BCM57712 network adapters, there are two possible scenarios that
can trigger pause frames to be generated: a host ring buffer is exhausted or the on-chip buffers are depleted. With RSS
enabled inside the system, it is possible to achieve better Ethernet throughput if no pause frames are being generated in a
case where a host ring buffer (of multiple RSS rings) is exhausted. The default is Disabled.
Quality of Service. Enables Quality of Service (QoS) to provide different priorities to different applications.
Recv Segment Coalescing (IPv4). Enable Receive Segment Coalescing (IPv4). Receive Segment Coalescing is an
offload technology that reduces CPU utilization for network processing on the receive side by offloading tasks from the CPU
to a network adapter.
Recv Segment Coalescing (IPv6). Enable Receive Segment Coalescing (IPv6). Receive Segment Coalescing is an
offload technology that reduces CPU utilization for network processing on the receive side by offloading tasks from the CPU
to a network adapter.
SR-IOV. Enables Single Root I/O Virtualization (SR-IOV).
